Overview
Affected versions of this package are vulnerable to Uncaught Exception due to an uncatchable ERR_INTERNAL_ASSERTION in the zlib streaming API, where the write callback queued by zlib.params() asserts that the native handle still exists after the stream has been destroyed. An attacker can crash the process by disconnecting while data is being compressed, so that pipeline() destroys the stream before the callback runs and the assertion error bypasses the stream's error event and the params() and pipeline() callbacks. Only applications that call deflate.params() while streaming to a peer are affected.
